The AFL will on Monday review a bizarre oversight by a field umpire which denied Sydney one point in Saturday night's game against Adelaide at the SCG.

The Swans should have been credited one point in the third quarter when Adelaide rushed through a behind.

However the field umpire never signalled all-clear to his goal umpire colleague, which meant the behind was never signalled despite the Crows kicking out.

The missing behind made no difference to the eventual outcome, as Adelaide won by 24 points.

An AFL spokesman said the umpiring department would on Monday review the incident, but confirmed scores could only be amended after quarters and not two days after the game.

In a separate incident in the same quarter, Sydney's Martin Mattner was denied what appeared a great goal on the run, only for the goal umpire to signal a behind.

Meanwhile, Hawthorn coach Alastair Clarkson could also find himself under review after he made a veiled criticism of an umpire after his side's loss to Geelong at the MCG on Friday night.

The Hawks were on the wrong end of a 10-4 free kick count at quarter-time and asked if he thought his players were unlucky, Clarkson said: "He's a good player that No. 17, wasn't he? He's a ripper."

The remark was a reference to umpire Justin Schmitt.

The AFL spokesman said the umpiring department would discuss Clarkson's comment on Monday, but the Hawks coach could be sent a letter asking to explain himself.
